CLOVER- HULLlNG ATTACHMENT FOR THRASHlNG-MACHINES.

SPECIFICATION forming part of Letters Patent No. 330,736, dated November 17, 1885.

Application filed April 6, 1885. Serial No.161,256.

To aZZ whom it may concern:

Be it known that I, WILLIAM S. REEDER, of the city of St. Louis, in the State of Missouri, have invented acertain new and useful Improvement in Clover-Hulling Attachments for Thrashing-Machines, of which the following is a full, clear, and exact description, ref erence being had to the accompanying drawings, forming part of this specification, and in which- 4 Figure l is a side elevation of the concave, an end View of the cylinder, and a vertical section of part of the frame of the machine. Fig. 2 is an inside or face View of the back I 5 section of the concave. Fig. 3 is a section taken on line 3 3, Fig. 2. Fig. 4. is a section taken on line 4 4, Fig. 2. Fig. 5 is an inside or face view of the front section of the concave. Fig. 6 is a section taken on line 6 6, Fig. 5. Fig. 7 is a section taken on line 7 7, Fig. 5. Fig. 8 is asection of one of the teeth, taken on line 8 8, Fig. 7. Fig. 9 is a detail view of a modification.

My invention relates to an attachment for hulling clover-seed, that can be applied to an ordinary thrashing-machine bysimply removing the concave of the thrasher and substituting the attachment, which is aconcave of peculiar construction. The same cylinder that is used on the machine for thrashing wheat is used with my improved attachment for hulling clover-seed.

My invention consists in features of novelty hereinafter fully described, and pointed out in the claim.

Referring to the drawings, A represents the cylinder, and B part of the frame-work, of an ordinary thrashing-machine.

0 represents the back section, and D the front section, of my improved concave, the latter of which is held in place in the same manner as the sections of the regular concaves of thrashing-machines thatis, by fitting in grooves at its endsand the part 0 is held in place in like manner, and by means of lugs I, formed upon it and bolted to the frame B.

The inner surface of the part or section D is serrated longitudinally, forming projections J, that present forward, or opposite the direc- 50 tion in which the cylinder is rotating. In

order to accomplish the desired result perfectly, the teeth should be presented in a direction opposite to the direction in which the contiguous face of the cylinder moves, and it is also desirable that they should be as angular as possible, and extend the entire length of the section. (See Figs. 5, 6, and 7.) In this part of the concave are secured teeth L, similar to those of an ordinary thrashing-machine, except they are roughened, as shown in Figs. 6, 7, and 8, and they act to prepare the stalks and pods for the reception of the back portion, 0, of the concave. This portion or section D of the concave takes the place of the ordinary concave of the thrash- The section 0 is a continuation of section D, and has ribs N, which are preferably in line with the teeth L, (see Figs. 2 and 5,) and are serrated on both sides, form ing transverse projections 0. These ribs are preferably bolted to the section 0, as shown in Fig. 4, though they may be cast in one piece with it, as shown in the modification, Fig. 9. Between these ribs the section is longitudinally serrated,formingprojectionsP.

The straw or stalks, being broken up in passing through the section D, by the teeth projecting therefrom and from the cylinder A, is forced, with the pods, through the solid grooves of the section 0, formed by the ribs N. The presence of the broken stalks in the section 0, where the seed is rubbed out, is

found to be of great advantage in removing the danger of injury thereto, which is inevitable where the straw is separated from the 5 pods and the pods are passed through another rubber or huller having sharp rubbing or grating surfaces, as in this case.

The broken straw or stalks act as a rubbing moving bed, and serve to assist in removing 9 the seeds from the pods, at the same time preventing the seeds from being cracked and broken, as above stated.

I am aware that it is not broadly new to provide the inner surfaces of concaves forthrashing-machines with longitudinal teeth or serra tions, and do not claim such as my invention.

I am also aware that transverse ribs have been arranged upon the inner surfaces of concaves, between which the teeth projecting radially zoo from the cylinder work, said ribs being pro the transverse ribs N, having tlie'angular vided with laterally-projecting ribs or teeth. serrations O, and the section D, having the In such devices as heretofore constructed the longitudinal teeth J and the roughened teeth teeth have been of inverted-V shape, and this L, said teeth 1? and J and serrations O hav- 5 is not the equivalent of my invention. ing their sharp edges presented in a forward I 5 I claim as my inventiondirection, as set forth.
